Taylor Swift performs on stage for the 1989 World Tour at CenturyLink Center on May 20, 2015 in Bossier City, Louisiana.

As promised, Taylor Swift released a concert documentary about her hugely successful 1989 World Tour this holiday season. It's appropriately titled The 1989 World Tour, and is currently streaming on Apple Music exclusively.

Centering around her tour stop in Sydney, Australia, the film is filled with live performances of songs from her blockbuster 1989 album, backstage footage, interviews with her famous friends, and narration from Swift herself.

Here are 10 fascinating moments from The 1989 World Tour documentary.

1) In the movie, Swift explains how she recruited that endless parade of special guests for her tour. "Some of the special guest appearances were planned months in advance. I would reach out and I'd say, 'I love your music. Here's the schedule, here are the tour dates. Which ever one you want to come to, we'd love to have you.'" Swift notes that after Mick Jagger joined her onstage, people were more likely to say yes.

2) Not all of the special guests were planned so far in advance, however. In the documentary, Swift reveals she recruited John Legend to join her onstage just 40 minutes prior to showtime after spotting him in the audience.

3) Rehearsing backstage with Alanis Morissette in one scene, we see Swift urging the singer-songwriter to mime hitting her during the lyric, "It was a slap in the face." Taylor explains her insistence on the slap to Alanis as such: "Bruises heal, but moments last forever."

4) Anyone who showed up at the 1989 Tour is familiar with the colorful audience bracelets that lit up in synchronization during the show. What they might not know, however, is that Swift let her guests control the bracelet colors during their visiting performances.

5) In an interview portion of the film, Lena Dunham shares her memory of Taylor playing 1989 for her pre-release date: "I made her play it over and over until she finally said, 'I don’t want to play it anymore.'"

6) In one scene, Swift explains snagging Mick Jagger for a duet on "(I Can't Get No) Satisfaction" at her Nashville tour stop. "My dad's like, 'My friend swears he was sitting next to Mick Jagger at lunch yesterday.' So I text Mick and I said, 'Hey are you in town? I'm playing a show tomorrow night, do you want to come out and sing "Satisfaction"?' And he just writes back, 'What will I wear?'"

7) At 1:17:00, Swift's friends -- from Selena Gomez to Haim to Cara Delevingne -- share stories on what a "typical hang with Taylor" is like. Hints: Dancing, and lots of cats.

8) Swift shares she wanted to duet with Mary J. Blige on "Doubt" after hearing the soul queen sing it at a Grammy party. "I'm so doubtful of myself constantly -- no matter what I achieve, no matter what happens," Swift said. "So that song struck a chord with me. I remember thinking, 'That would be amazing if I could ever sing that with her.'" And in L.A., they did.

9) Swift heaps massive praise on her "Mirrors" duet partner in one scene. "I think Justin Timberlake is the closest thing our generation has to Frank Sinatra," she said, comparing one actor-singer to another. "I honestly think he's one of the greatest musicians of our time."

10) Post credits fun! Taylor shares her plans for 2016, saying, "Maybe I'll jut eat carbs for the next seven months. I don’t have to wear any crop tops." She also stands in front of the camera holding her two cats while one of them desperately tries to escape. The film ends with the words, "No cats were harmed in the making of this tour. Just one pop star."
